Title: Photoproduction of K + K meson pairs on the proton

Abstract

Here, the exclusive reaction $$\gamma p \to p K^+ K^-$$ was studied in the photon energy range $$3.0 - 3.8 \mbox{ GeV}$$ and momentum transfer range $$0.6<-t<1.3 \mbox{ GeV}^2$$. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. In this kinematic range the integrated luminosity was approximately 20 pb$$^{-1}$$. The reaction was isolated by detecting the $K^+$ and the proton in CLAS, and reconstructing the $K^-$ via the missing-mass technique. Moments of the di-kaon decay angular distributions were extracted from the experimental data. Besides the dominant contribution of the $$\phi$$ meson in the $P$-wave, evidence for $S-P$ interference was found. The differential production cross sections $$d\sigma/dt$$ for individual waves in the mass range of the $$\phi$$ resonance were extracted and compared to predictions of a Regge-inspired model. This is the first time the $t$-dependent cross section of the $S$-wave contribution to the elastic $K^+K^-$ photoproduction has been measured.
